Please do not resort to changing so many parts. It could be the bendex in the starter motor. Please get it checked. If negative, then you can try other parts. But to the best of my knowledge it is the bendex.

My 2002 Trailblazer stalled while running, and after I pulled over, starter new would not engage and is stuck in park.

I believe your timing belt broke and destroyed your engine. Also your starter could be jammed

On my 2002 Trailblazer, when I start the engine, all my dash warning lights on and gauges stop working, the speedo and tach still work.

There is a known problem with the ignition starter switch that causes this, this is the switch that the ignition key operates when you turn it.

My 2002 Chevy Trailblazer loses power at times. I wil be driving 60 MPH then suddenly I cant drive more than 30MPH it sounds like I have a flat tire. If I shut my car off and wait about 5 minutes it runs...

the running issue seems to be the convertor clogging up. need to have backpressure test done to see for sure. the electrical issue sounds like the ignition switch or the orange ,pink,or yellow wire going to the switch. both are common problems with the trailblazer.NOTE if the vehicle has less than 80000 miles the convertor will still be under factory warranty (EPA guidelines)

I have a 2002 Trailblazer. This has happened 3 times in about 6 months. Usually it works fine, but sometimes I turn the ignition key and all accesories come on, but nothing on the engine. Eventually...

you could have a dead spot in your starter. The next time this happens, have someone turn the key and tap on the starter with a stick or a wrench -- this can sometimes jolt the starter out of the dead spot and get you started. If this works, get your starter replaced and you should not have any more problems. If you can, take it to a mechanic before it happens again and see if they come up with the same diagnosis. If the mechanic finds it is the starter, get it replaced ASAP so you don't get stuck somewhere.

In my 02' Trailblazer oil pressure gauge goes below 0

I have this same problem with my 2002 trailblazer; however, I goofed up and had a mechanic look at it, since I was perplexed as to what was going on with it. He told me the oil pump needed replacing and it ended up costing me around a $950. Needless to say, it still happens. A grand down the drain - it wasn't the oil pump. The oil level is always good. This generally occurs when I've run the vehicle for a while and then come to a stop. It occurs quite often during the spring/summer and doesn't happen all that much during colder months.

06 Trailblazer that will not start

Try putting the geashift in neutral when starting the truck. If it starts every time this way, your neutral safety switch or park interlock switch is broken. Let me know if this helps :)
